Tweak your boost levels with this GripTec "upper" LT4 pulley upgrade for your 1.7L LT4 supercharger. The stock LT4 blower came on V3 CTS-Vs, 6th gen Camaro ZL1s and of course the C7 Z06. This bolt-on upgrade allows you to change the spin-rate of the supercharger. A Griptec upper pulley upgrade is a cheap and effective way to boost power.

ZPE (the company behind the GripTec pulley system) has their own mounting "hub" (the ZPE hub) that's required to use this LT4 pulley. If you already have the ZPE hub you can simply buy a pulley by itself. Otherwise you can buy a pulley and hub combo or you can buy a hub separately. The hub comes with a set of 10 titanium screws for weight savings and strength.

The GripTec pulleys are made from billet 7075-T6 aerospace grade aluminum which is Stronger and harder than 6061-T6. What makes these LSA pulleys really shine is the "GripTec" technology that's applied during the machining process.

GripTec is a micro-machining technology that allows for maximum grip force to be applied to the LT4 supercharger pulley without damaging your blower belt. More importantly the GripTec technology essentially deletes belt slip on the blower allowing all of the crank's power to be transferred to your blower via the pulley.
